They may have watched the legendary Lufthansa heist in “Goodfellas” — but these Bonanno hoods want no part of it in real life.

Four of the five reputed Bonanno crime-family bigs swept up in a January bust that netted the famous heist’s alleged mastermind are negotiating plea deals to settle their cases, according to a Brooklyn federal court filing.

That would leave the accused Lufthansa point man — capo Vincent Asaro — all alone to face trial for a slew of raps including murder and racketeering that could put him behind bars for life.

Lawyers for three of Asaro’s co-defendants — acting capo Jack Bonventre, soldier John Ragano and capo Tommy DiFiore — argued that publicity surrounding the 1978 JFK robbery was too prejudicial and that their clients were involved in more mundane crimes with no connection to the famous heist.

They successfully had their cases severed from Asaro’s and are now hammering out deals, according to a filing by DiFiore’s ­attorney, Steve Zissou.

Asaro’s son, Jerome, is also part of the “global settlement” currently being negotiated, according to the filing.

Vincent Asaro was depicted in Nicholas Pileggi’s book “Wiseguy” — on which the movie “Goodfellas” was based — as the gangster who took the hapless “Spider” character to get patched up after he was shot in the foot by Tommy DeSimone (portrayed by Joe Pesci in the film).
